Abstract

A thermoplastic molding composition comprises, based on the total of components A to C and, if desired, D and E, which in total give 100% by weight,a) as component A, from 10 to 98% by weight of at least one aromatic polyester,b) as component B, from 1 to 50% by weight of at least one particulate graft copolymer whose soft phase has a glass transition temperature below 0° C. and whose median particle size is from 50 to 1000 nm,c) as component C, from 1 to 50% by weight of at least one copolymer made from the following monomersc1) as component C1, from 50 to 90% by weight of at least one vinylaromatic monomer, andc2) as component C2, from 10 to 25% by weight of acrylonitrile and/or methacrylonitrile,d) as component D, from 0 to 25% by weight of other compatible polymers hormogeneously miscible with components A and/or C or dispersible in these, ande) as component E, from 0 to 10% by weight of conventional additives, such as UV stabilizers, carbon black, pigments, oxidation retarders, lubricants and mold-release agents.Moldings made from these molding compositions and used in motor vehicle interiors are also described, as is the use of the molding compositions to produce the mold…
